FWN, my take-away from your posts is that he's not 100% serious about sobriety. For a start he asked you to find treatment he could do while still working. It's not your job, and he may have said it to appease you.
I'm sure he thinks he's being serious but that's not the same as rock solid determination to become sober. The real thing can be traumatic, gut-wrenching, and leave little effort for anything else. Recovering As can be hard to live with at first.
Is there any possibility of him living somewhere else until he can show sustained sobriety for a year?
I understand your circumstances don't give you a wide range of choices. If it were me, I would stay as close to support of F&F as possible, but there are many factors to consider. At least think about what contingencies you can put in place if you need to separate.
